Toposolid makes Revit useless

[simon_kveen]

Going from toposurface to toposolid have completely ruined Revit. 

The workflow is incredibly slow when working with toposolid. I mean really, reeeally slow. 

Bring back toposurface and get rid of toposolid - we don't need it.

It is impossible to please everyone but I am not so sure it is THAT bad. If one is used to the workflow of modeling site in a separate model (which many users could not understand and used to complain about), one can still use toposurface in a previous version and do all the cuts and fill there. Moreover, 

• one can also link it to the models in 2025 version and keep it as a surface 
• and/or bind it and just keep it as a surface
• create a new solidtopo out of it
• Either way, the cut and fill carries over

Everything worked fine with toposurface. No need to change anything. 

Working with two different versions of Revit is not a solution.

• You can not link your building model that you made with Revit 2025 into your site model from 2023. That is not possible. 
• Yes, you can create a new toposolid of the toposurface, but have you ever tried editing that toposolid? It takes a whole year just to change the value of a single sub-point.

Whether it was in the past version or new version, the the proper workflow for topo7site was and is still to model in a separate model. if that separate model is 2023 or 2025 what is the difference?!

• Yes you can...read again the previous reply, you have linked the 2023 into a 2025 blank site. from this point on you would link the 2025 site into your building model since that would be the main model and not vise versa. But if you are that pickiny, the 2023 is linked into a 2025 so what prevents you from linking the building into that?!
• Yes I have and with all due respect you are literally exagurating. A Year? Seriously?

When it used to be only toposurface, some used dynamo to transform that into solids/masses/floors while many complained why this option is limited to the few who know how to use dynamo. It was such a fuss that the topic went into seminars, AU Classes, Youtube and all over where Revit was a topic. Instead of having access to both worlds by learning a little bit of dynmo, users kept demanding to have the solid version. Now that Autodesk have decided to give the people what they want, I read negative comments, critcizm and complaints because the Toposurface was so much better. 😄 and I bet many of those complaining now are some of those who complained in the past. I am not saying you are one of those but just saying thats how it seems things are

Wow, ok.... You mean this is a good solution? Should I hit the accept solution button?

Autodesk offers a 30 days free trial for Revit you know. You should try it sometime. Let me know how it goes.

No you don’t because there is no problem to solve the first place. The suggested workflow was not specifically suggested for you to use but shared for those who come across this post to consider.

The topography worked fine in the past even when some were unable to live with it and it works fine today even when you are unable to coop with it and as mention before most of those who complained in the past are the same who complain today.

I install revit 2025,

  with more than 100 points (average topo site )  it become a nightmare, 

they just fail,   never install or use the 2025 version  it  take around  16 secondes to move a single point  every action take between 5 to  20 secondes to regenerate, 

the sadest things you can have single geometry plane anymore , like water or to make some thin layers,  

Autodesk will never admit that they fail miserly  on this one,

try the same site with  2022 take  a second to compute, 

there is no solution, or walk around ,  pray they fix the bug sofware in 2026 , for now stay with  2022 

never ever click the "accept solution button" until it's fix, 

Autodesk really ruined a software they bought back in 2010,

Soo easy to blame the people who complaint,   the site create since the first version of revit back  in 2001 was not perfect, but at least was fast 

now it still not perfect but it's crasy slow,  

typical of autodesk response ,  keep complaint we don't care , we make billions,   no problems , go use archicad, if you are not happy, 

that not how it work ....

the topo in 2025 is poorly program and implemented , just fix it ,   wait for  2026

Try the Ideas forum. That's where Autodesk looks for suggestions.

for 2026  :

Enhanced Site & Topography Tools: Site modeling continues to improve. After the debut of Toposolids in 2024 for more flexible landscape design (Revit Product Enhancements, Benefits & Roadmap | Autodesk), Revit 2026 adds further refinements to terrain modeling. Toposolid enhancements make it easier to sculpt and grade sites with complex conditions. Smoother shading and editing controls provide more realistic terrain visualization and simpler modification (a trend started with 2025’s toposolid smooth shading option (What's New in Revit 2025)). These tools enable architects to incorporate site context more accurately and early in the design process (What's New in Revit 2025). Additionally, a “simplify topography” function (inspired by earlier releases (Revit Product Enhancements, Benefits & Roadmap | Autodesk)) helps reduce excess points on imported topo, boosting model performance while retaining essential site features.

doesn't seem to be debug  , (need a test )   for now,   we stay on Revit 2022.

no significant improvement anyway,

For the record, if you are working in the ACC, you cannot host two models of different versions. So your solution to work with toposurfaces in 2023 and then drop them into a later version does not work. This also would completely mess up any form of collaboration in which the architects are working in a later version if you are working in 2023. This is a total non-starter for anyone working in the ACC, or collaborating across disciplines.
